Description H 2005-01-27 06:24:42 UTC
See bug #4112 for environmental descriptions and other information.

/proc/acpi/battery/BATX/state on Dell Latitude X300 fails to show the capacity
of the battery, and it's discharge/charge rate. The charging state is shown
correctly.

Output of /proc/acpi/battery/BAT1/state without AC adapter attached:

root@linkin:~; cat /proc/acpi/battery/BAT1/state 
present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            768 mA
remaining capacity:      0 mAh
present voltage:         0 mV

Output with AC adapter attached:
root@linkin:~; cat /proc/acpi/battery/BAT1/state 
present:                 yes
capacity state:          ok
charging state:          charged
present rate:            0 mA
remaining capacity:      0 mAh
present voltage:         0 mV

This bug is related to the #4112 BIOS bug of the X300, and can (as mentioned in
that report) be fixed by editing the DSDT and compiling it into the kernel.
